In the meantime Google already has working self-driving cars, as well as Tesla Motors.

And Google is using AI to enhance its search algorithms and everything else...

The terminology is also shifting slightly, Artificial Intelligence, then Machine Learning,
and now is Machine Intelligence

Home — TensorFlow"TensorFlow is an Open Source Software Library for Machine Intelligence""TensorFlow™ is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API. TensorFlow was originally developed by researchers and engineers working on the Google Brain Team within Google's Machine Intelligence research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well."

"RankBrain is the nickname given to the proprietary artificial intelligence (or AI) used by Google to handle search queries. The AI may never be given a formal name, or maybe RankBrain will stick, but for now, it’s the name being used for the artificial intelligence that’s handling 15% of Google’s search volume.An important distinction to be aware of is that RankBrain is not (currently) a standalone technology at Google – it’s incorporated directly into the existing algorithm that Google uses to rank web pages.
